I've decided to pick up a Delta Platoon VF-31. But I can't decide which. I was thinking a Messer but the ugly head combined with the fact that Messer didn't actually do anything in the show leaves me a little unsure. I'm thinking maybe the Arad or the Mirage.

As far as the show goes I just finished the episode where Messer bites it but haven't got much further yet. Are their any characters that I'm gonna think are awesome by the end of the show and regret not buying their Valk?
